cheers for your input but all i have done is remove the salt from my grow, the nutes they are on they were already on but at lowered concentrations... The basis of this style of growing which has been patented and trialled for many years is you grow with 1000ppm-2000ppm of sea salt alongside 1/4 - 1/2 strength nutrients (hydroponically).. If i was growing in soil i wouldn't be experimenting as i've tried most combinations of things and would be confident i would never lose a plant but i am new to dwc. i have figured since posting in this thread that the reasons i am not getting great results is the salt i should be using is 8 times better (sea 90).. seeing as i have scraped along with the wrong salt, the salt switch should make all the difference...
so in theory germinating in 15000ppm sea 90 is only 225 ppm of trace elements.... considering i'm using RO that is just a hearty background ppm. thats not including the high level of NaCl which accompany it and are necessary for those trace elements to be absorbed.. thats why i have read the suggested levels to be this high, and have read a lot higher...... its similar to growing on volcanic soil but its water.. You don't need typical npk contributions, just a splash on N in veg and P in flower... The idea is to grow much more chemically complex plants that possess great attributes such as greater nutrition, flavour, oil production, resistance to pests and shorter ripening times... If done properly it supposedly will increase your yields but i am more interested in growing organic hydroponically with a cleanish looking rez. oh how much easier would it be if i just didn't care...
Oh, it makes more sense now. I really didn't understand before, but you seem to know what your talking about and the Sea 90 is probably the major factor your missing, have fun and good luck.
